RENNTECH FOR SLK350 V6

---

RENNTECH's new $3995 performance PKG1 for the 05-08 SLK 350 boosts the output of the 268 hp V6 to over 300 hp. That's 40 horsepower for under $4000!

This level of performance and torque comes from new RENNTECH headers and a RENNTECH ECU upgrade, which also raises the car's top speed from the factory-limited 155 mph to over 170 mph. As the copy above states: this package will change the way you look at Mercedes' 350 series cars.

Currently available for 05-08 SLK350 and GLK350.

750 HP SLR - ON THE DYNO

---

The video above shows a fantastic Switzer-prepared SLR McLaren coupe putting out 600 hp at the wheels - that's almost 750 hp at the crank!

This SLR makes use of RENNTECH's SLR PKG1 performance upgrades and the latest version of the RENNTECH's SLR McLaren software. Each SLR engine is assembled by hand at AMG, of course, and there are sometimes slight variances, but this is still a STRONG build - Switzer (our primary Ohio dealer) did a fantastic job getting the most out of this McLaren on pump gas (RENNTECH advertises 722 hp, or just under 580 hp at the wheels).
